dont care about sharing database just want to use wp header and footer

I have read and re-read most of the articles on how to integrate wp and bb. I got it to work but decided I dont care about having users shared between both. Now I have seperate databases which is fine by me.

1. I would like to make my bb forum look as close to my wp theme as possible and have read that the best way is to edit the bb template files correct?

2.Is this done via the template folder on the server?

3. Is there a spot on bb admin to edit files?

Can someone please post an EASY way to integrate the look and feel like how to remove the sidebar in bb?
